The application bypasses the OS network stack, and constructs network packets directly in a buffer shared with the network hardware, achieving a ten-fold throughput improvement. He writes: "Using this technique, we can send or receive uncompressed UHD 2160p50 video (more than 8 Gbps) using a single CPU core, leaving all the rest of the server's cores free for video processing." This is part of a broader BBC project to develop an end-to-end IP-based studio system.
